I’m not sure this is a bug, but it’s a different behavior than Google Sheets/Forms. I have a link in a worksheet (using HYPERLINK) to open a submission form (using a Form View). I added a new column to the worksheet and then the URL to the form changed (making the previous link no longer work):
This could be an issue if the link to the submission form was shared and bookmarked by a lot of employees. I’d prefer that the share url for a form view remain working even after changes are made to the form or the underlying worksheet.
